# dirname > Calculates the parent directory of a given file or directory path. > More information: . - Calculate the parent directory of a given path: `dirname {{path/to/file_or_directory}}` - Calculate the parent directory of multiple paths: `dirname {{path/to/file_a}} {{path/to/directory_b}}` - Delimit output with a NUL character instead of a newline (useful when combining with `xargs`): `dirname --zero {{path/to/directory_a}} {{path/to/file_b}}`
